3. Random coloring a hollow mass of yarn having inner and outer surfacescomprising continuously rotating the mass about-its axis, creatingacurrent of air'through a limited portion of the mass from one surfaceto. the other and introducing coloring fluid'into the current of air asit passes through the mass.

4-. The herein described method of coloring a hollow of yarn havinginner and outer surfaces consisting in applying suction to a portion ofone of said surfaces and simultaneously applying the coloring matter toa portion of the other surface and simultaneously rotating said mass.

The herein described method of coloring a mass of yarn consisting inapplying nozzles to the interior and to the exterior of the mass ofyarn, producing suction in one of the nozzles, and supplying coloringmatter through the other nozzle.

6. The herein described method of coloring a mass of yarn con iisting inapplying nozzles to the interior and to the exterior of the mass ofyarn. producing suction, in one of the nozales and supplying coloringmatter through the other nozzle and rotating the yarn relatively to oneof the nozzles.

comprises passing an unlimited 7. The method of spotting yam "wh chdyeing liquid into, through and limited partof a wound mass of yarn withsuch rapidity that no material part of the liquid soaks into theadjacent parts of the mass.

8. Random coloring a hollow mass of yarn having inner and outersurfaces, comprising creating a current of air through the mass from oneof said surfaces to the other, and introducing coloring fluid into theair current byapplying it to a limited portion of the surface of themass from which said current is entering the mass.

9. A method oj/random dyeing yarn in the mass, which comprises creatingan air current through the mass between posite surfaces thereof, andintroducing a co oring fluid into said air current by applying it. toalimited area of the surface of the mass through which said air currentis entering the mass, so thatthe coloring fluid is drawn by theaircurrent through a limited portion of the mass.

10. The method of spotting yarn, which comprises passing an unlimitedquantity of dyeing liquid .into, through and out of a limited part of awound mass of yarn between opposite faces thereof with such rapiditythat no material part of the liquid soaks into the adjacent parts of themass.

11. The method of spotting yarn, which comprises passing an unlimitedquantity of dyeing liquid into, through and, out of a limited part of ahollow ,wound mass of yarn between opposite inner and outer facesthereof with such rapidity that no material part of the liquid soaksinto the adjacent parts of the mass.

In testimony whereof I have hereunto set my hand.
